[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a traveling toy starting device that automatically starts a flywheel-type traveling toy.

(Technical issues with the invention) This invention accelerates the flywheel and starts the vehicle by simply placing a traveling toy using a flywheel in a predetermined position on the starting device and turning on a single starting switch. The technical problem is to provide a running toy starting device that can be realized.

(Means for Solving the Problems) In order to solve the above problems, the traveling toy starting device according to the present invention is a starting device that automatically starts the traveling toy by flywheel drive, and has the following requirements. Features.

(a) It includes a motor, a rotary wheel that is rotationally driven by the motor to rotationally drive the tires of the running toy on the starting platform, and a hook that projects above the starting platform and locks onto the running toy.

(b) The starting platform shall be provided with a bar-shaped switch member that can be pushed downward.

(c) The switch member has two stages: a first push-in position where the motor side terminal and the power supply side terminal are connected, and a second push-in position where the hook is moved in the direction of releasing the lock of the traveling toy. be provided so that they can be pushed in sequentially.

(d) A locking protrusion is formed in the middle of the switch member, and the starting platform engages with the locking protrusion and expands when the switch member is pushed in to allow displacement of the switch member. A locking member is formed.

(e) The locking protrusion and the locking member are formed to engage with each other at the first pushed-in position.

(Operations and Effects of the Invention) As described above, according to the present invention, the running toy is first placed on the starting platform and is locked with the hook to prevent the running toy from starting. Next, the switch member is activated. At this time, the switch member is pushed into the first push-in position and the second push-in position in sequence, but the motor-side terminal and power-side terminal are turned on at the first push-in position, so the rotating wheel rotates. death,
The tires of the traveling toy on the starting platform are driven to rotate, and at the same time the flywheel rotates, giving rotational energy to the tires. Further, when the switch member is pushed to the second push-in position, the hook moves in a direction that releases the lock of the running toy, so that the running toy starts due to the rotational driving force of the flywheel.

As described above, according to the running toy starting device of the present invention, the running toy can be started by simply placing the running toy using a flywheel in a predetermined position on the starting device and pressing a single starting switch. It is possible to realize running.

Furthermore, when pushing the switch member, resistance is applied at the first position where the locking protrusion and the locking member engage, so even if the switch member is pushed in with strong force, the switch member will not move to the first pushed position. It will not be pushed beyond the limit to the second pushing position. Therefore, the starting operation can be performed reliably.

(Example) Hereinafter, the traveling toy starting device of the present invention will be described in detail.

FIG. 1 is a perspective view showing the entire starting device of the present invention, and this starting device has a starting platform 1 and a housing 2 that covers the rear part of the starting platform 1. As shown in FIG. FIG. 2 is a longitudinal cross-sectional view of the starting device. Inside the starting platform 1, there is a motor 3, a rotating wheel 5 that is rotationally driven by the motor 3, and the inside of the starting platform 1 and the housing 2 are connected in the vertical direction. When the rear end portion 25b of the connecting member 25 is pressed downward by the switch member 10 penetrating and supported to be vertically movable and the pressing protrusion 11 of the switch member 10, the hook 23a at the tip of the hook member 23
It is generally composed of a starter 20 that retracts the battery downward, a battery 4 housed in a housing 2, and terminals shown in FIGS. 3a and 3b.

The rotating wheel 5 is rotatably supported inside the starting platform 1 and has a part of its outer peripheral surface exposed through an opening 6a on the top surface, and the output of the motor 3 is controlled by a crown gear 5b fixed to the rotating shaft 5a. It rotates upon receiving the drive torque transmitted from the shaft 3a.

The switch member 10 is configured to be movable toward the upper limit by penetrating the support hole 6b located behind the opening 6a and the support hole 7 of the housing 2, and is attached to the support frame 8 on the internal bottom surface of the starting platform 1. Thus, the lower end is supported. A spring 1 is installed inside the support frame 8.
2 is housed therein, and always urges the lower surface of the switch member 10 upward. A locking member 14 that can be engaged with a locking protrusion 13 on the front and rear surfaces is protruded from the front and rear parts of the peripheral edge of the support hole 6b, and defines a first pushing position of the switch member 10. The locking member 14 is made of a thin plate-shaped resin or the like, and when the switch member 10 is pushed further downward from the first pushing position, it elastically expands and the switch member 10 moves downward. It is configured to allow further displacement. There is a T on the other side of the switch member 10.
A letter-shaped plate electrode 15 is fixed horizontally,
The electrodes 15 are connected to terminals 3 arranged in parallel on the same peripheral edge of the support hole 6b according to the vertical movement of the switch member 10.
It is configured to turn on and off at 0. That is,
When the switch member 10 is located at the top as shown in FIG. 4a, only the protrusion at the upper end of one terminal 30a (motor side terminal) comes into contact with the electrode 15, as shown in FIG. 4b. When the switch member 10 is further pushed in a predetermined distance, both terminals 0
a and 30b (power supply side terminals) are in a contact state, and when pushed into the lower limit position as shown in FIG. 4c, the other terminal 30b is again in a non-contact state. When the switch member 10 is in the position shown in FIG. 4b (first pushed-in position), the locking protrusion 13
Once it comes into contact with the upper end and is locked, when it is in the position shown in FIG. do. As shown in FIG. 3b, one terminal 30a is connected to the motor 3, and the other terminal 30b is connected to the battery 4, and both terminals 30a and 30b are connected through the electrode 15. Thus, the battery 4 and the motor 3 are configured to be electrically connected.

As shown in FIGS. 2a and 2b, the starter 20 has a pair of hooks 23a that protrude in and out of a hole 6c in the front part of the starting platform 1, and is configured to be movable up and down by a rotation shaft 21, and furthermore, A hook member 23 that is constantly biased in the protruding direction by a spring 22 or the like

The connecting member 25 is rotatably engaged with the actuating piece 24 at the rear end portion 25b. When the switch member 10 is pushed to the position shown in FIG. 4c, the pressing protrusion 11 pushes down the operating piece 24 (FIG. 2b), so the connecting member 25 pulls down the hook member 23 against the spring 22. Ru. As a result, the hook 23a is retracted downward.

Reference numeral 9 denotes a positioning guide when attaching the housing 2 to the starting platform 1.

In the above configuration, as shown in FIG. 5, the running toy 40 having the tire 41 with a built-in flywheel is installed on the starting platform 1 so that the tire 41 is in contact with the rotating wheel 5, and the switch member 10
When the terminals 30a and 30b are connected to the electrodes 15, current from the battery 4 flows to the motor 3, and the rotating wheel 5 starts rotating in the direction of the arrow. Therefore, the tire 41 in contact with the rotary wheel 5 rotates in the forward direction, the flywheel that cooperates with the tire 41 rotates, and a large amount of rotational energy is stored due to its inertia. On the other hand, the hook 23a is in contact with the tip of the traveling toy 40 and prevents it from starting. In this state, switch member 10 is further moved to the fourth position.
When pressed down to the position shown in FIG.
As a result of this action, the hook 23a is retracted from the hole 6c, and the toy can be unlocked and started.
